3 claims. l

This invention relates to a novel construction of door holder primarily intended for usewith horizontally swinging vertically hinged doors to enable a door to be retained rigidly in an open position while a mortice is being cut therein and a lock assembled in the door.

More particularly, it is an aim of the present invention to provide a device which will not mar a door while holding it rigidly in an open position and to replace a chisel or block which is ordinarily driven under a door for this purpose and which frequently results in chipping and otherwise damaging the veneer and other parts of the door.

Still a further object of the invention is to provide a door holder which will effectively prevent the door from swinging out of engagement therewith while the holder is in an operative position and which will likewise prevent the holder from slipping outwardly of the door;

rStill a further object of the invention is to provide a door holder capable of being quickly and easily applied to or removed from a door without damage to the door or floor surface disposed therebeneath yet which will effectively function to retain a swinging door rigidly in an open position.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the' drawing, illustrating a presently preferred em bodiment thereof, and wherein:

Figure 1 is a top plan view showing the door holder as it will appear in an operative position;

Figure 2 is a longitudinal vertical sectional viewkr thereof taken substantially along a plane as indicated by the line 2-2 of Figure 1 and showing the holder engaging a corner of a door;

Figure 3 is a cross sectional view of the holder in an operative position taken substantially along a plane as indicated by the line 3--3 of Figure 2;

Figure 4 is a fragmentary longitudinal sectional view showing the holder in a folded, inoperative position, and

Figure 5 is an end elevational view on an enlarged scale of one element of the holder.

Referring more specifically yto the drawing, the novel door holder in its entirety is designated generally 6 and includes an elongated bar 'I which is provided with integral upstanding side walls 8 which rise from its side edges and which extend from the end 9 of the bar 'I beyond itsA opposite end I0. Said side walls 8 are enlarged adjacent the end I0 of the bar I to provide portions which are disposed below the bottomsurface of the bar and which form integral extensions of the walls 8 which extend beyond said bar end I0 to form laterally spaced arms or furcations I I which are provided adjacent their free ends with aligned openings I2. The bar l is provided with a plurality of longitudinally spaced threaded openings I3 for selectively receiving a setscrew I4, prefer- -ably of the Allen type, which is adapted to be threaded upwardly into any one of the openings I3 and which is provided with a pointed end I5 which projects upwardly from the upper surface of the bar 1r and the opposite end of the setscrew I4 is disposed substantially flush with the underside of the bar 1.

An elongated lever I6 is provided at one end thereof with an integral extension I'I which projects at substantially a right angle from the plane of the lever I6 and which has a rounded, convexly arced outer side and a rounded free end so that said portion I'I forms a cam element. The lever IB is provided with an opening I 8 which is disposed substantially centrally of the junction of said lever and the cam element I'I and the cam element is provided with a second opening I9 disposed between the opening I8 and its rounded free end 20 and preferably closer to the opening I8 than to the end 20. The length of the cam element I 'I and the width of the lever I6 at the end thereof which joins with said cam `element is less than the distance between the furcations II so that said end of the lever and cam element may be disposed between the furcations and with either the opening I8 or the opening I9 in alignment with the furcation openings I2 to receive the shank of a pin 2l which extends loosely through said openings and which is provided at one end with a head 22. It will thus be readily apparent that the lever I6 may be detachably connected to the furcations II by the pin 2I and pivotally supported thereby relatively to the bar 'I and so that when the lever I6 and bar 1 are disposed in substantially the same plane and in extended positions relatively to one another, the cam element I'I will extend downwardly from the lever and from the furcations I I. Likewise, the lever I6 may be swung upwardly in a counterclockwise direction to substantially an upright position and at approximately a right angle to the plane of the bar 'I,

as illustrated in dotted lines in Figure 2, to thereby position the arcuate, outer edge of the cam element I'I in substantially the same plane as the bottom edges of the furcations II, as seen in dotted lines in Figure 2. With the partsv thus disposed, theA end 9 ofthe bar las theleading 3 end of the door holder may be inserted under a bottom edge of the outer lower corner of a door, a portion of which is illustrated in Figures 2 and 3 at 23. The outer end 9 of the bar 1, which is rounded on its under side, will rest upon the floor or other surface 24 which is disposed beneath the bottom edge 25 of the door 23 and the outer, free end portion of the bottom edge 25 of the door will then be disposed above the bar 1, which bar is ofsufiicient width'to accommodate a door of maximum thickness 'between its upstanding side walls 8, such door being illustrated at 23. Assuming that the pin 2l engages the opening I8 and that the lever I6 and cam rL1 are disposed in their dotted line positions of Figure 2 and that the bar 1 is disposed Aunderf'the bottom edge 25, so that the outer edge of the door 23 is disposed adjacent end i0 of the'bar'1, with the parts thus disposed, the lever fll may then be swung downwardly and outwardly of the door-23 in a-clockwise direction as seen in Figure 2 on the pivot pin 2| and in so moving, the convexly rounded outer `surface of the cam element lil will slide and fulcrurnon the .oor surface .24

and .elevate the furcations Il and the adjacent end of the bar l with said bar fulcruming on the floor surface 2li on its roundedend 9. .As .the lever l@ continues to swing downwardly and out- Wardly of the `door ,23 the rounded outer end or edge 20 -of the cam element .Il will move into contact with .the floor 2A and as the lever l5 approaches its full lineposition of Figuref2 said rounded end .2li will pass across a vertical line extending downwardly from the axis of the pin 2l or .across the vertical, dead center .position of the ,cam element Jl to .lock the door holder in its-operative .full line position of .Figure 2. During this swinging-movement of the lever i6, the

bar Al Land the parts formed integral therewith will swing upwardly .onvthe bar vend 9 which will L fulcrum .on the oorsurface`24 so .that when the lever .E6 has reached .its full line position vof "FigureZaportion ofthe bottom edge of the door 23, adjacent .the free vedge of said door, will be disposed between the walls and the pointed end l5 of the setscrew I4 will have penetrated a lpart of the bottom edge`25 so that said setscrew will prevent the doorholder 'G from sliding outwardly o'f the door .23 in a direction from left to Yright .of 'Figure 2 .while the parts thereof areA moving from their dotted'line to their'full/line positions and after the parts are in their full line ,positions .of 'Figure`2, the'walls 8 will e'iectively prevent the door'23-from swinging in either direction relatively to the'bar '7. With the door 23 thus wedged .in an open position "by the door holder E, it will be readily apparent that it will be held rigidly so that a morticemay be cut in the door and a'lock assembledthereonwithout the "door moving while this work is Ybeing laccomplished and any other--operationmay beperformed on the doorwithout removing it from-its hinges.

With the vpin 2l engaging 'the opening i8 `the doorholder 6 will effectively functionforrigidly retaining -the door in an'open position, vthe v'bottom edge of which is vdispose'dlas much as an inch andone-half vabove the floor surfacef24. -By applyingthe pin 2i tothe openings |-2 and the opening i9 r-of the @cam element lll'l, it will Ibe readily apparent that the bar 'l will vbe nearer the floor 2li-at its end Hl whenthe'camelement lil y-is -inits fulllinepositionof -Figure 2, so that the `door holder l5 lwill thenfmore readily lfunotion for accommodating ya door, 'thebottom `'edge ofw'hih 4disposed@nearer the ifloor Vvsurface 124.

4 Likewise, for doors which are disposed nearer the floor surface 24 the anchoring screw 14 is preferably positioned in one of the other openings !3 located nearer the lower end 9 of the bar l.

With the threaded end of the setscrew I4 disposed substantially flush with the under side of the bar 1, after the lever I6 has been swung back to its dotted line position of Figure 2 so that the door hdlder\.6 may be readily detachedfrom engagement with the door 23, the "lever lI6 may then be swung clockwise until it is disposed Various modifications and changes are con- 'templated'and' may 'obviously be resorted to, with- ;outldepartiug from the spirit or scope of the invention as hereinafter defined by the appended claims. p
